Abstract: 352,994. Thermionic valves. DIXON, E. J. C., Barnhill, Preston, Harrow, Middlesex. April 12, 1930, No. 11625. [Classes 39 (i) and 40 (v).] Thermionic valves are provided with two output electrodes or anodes A<1>, A<2>, Fig. 2, and with two control electrodes or grids G<1>, G<2>, each grid being associated with one anode and conductively connected to a stabilizing electrode associated with the other anode so that the coupling due to the capacity between one grid and its anode is neutralized by the coupling due to the capacity between the other anode and its stabilizing electrode when the two grids are excited in phase-opposition as in " push-pull " circuits. The stabilizing electrodes may be grids S<1>, S<2> on the sides of the anodes remote from the grids G<1>, G<2> giving a capacity between the grid G<1> and anode A<1> equal to that between the grid S<2> and anode A<2>. When used as an amplifier with the grids G<1>, G<2> excited in phaseopposition as in Fig. 6, the alternating potentials on the anodes are in phase-opposition and induce balancing alternating potentials on each grid G<1> and the electrode S<2> connected to it. Chokes 6, 7 are inserted as shown and an external screen 8 is provided. The connections C<1>, C<2>, Fig. 2, are short and are connected to the input leads at their centres. The cathode may be indirectly or directly heated and may comprise two straight filaments C, Fig. 4, connected in series, the other electrodes, being flat vertical plates supported in cups H on silica frames F carried by supports K on the silica envelope E. Input and output leads are brought out at opposite ends. An additional screening grid may be positioned between each grid G and its anode A, the capacities between the anodes A and electrodes S being correspondingly decreased by smaller size, or greater distance from its anode, of each electrode S. In an oscillation generator, the input and output circuits 3, 1, Fig. 6, are rigidly coupled and the leads 10, 11 between the circuit 3 and the grids G<1>, G<2> have a length so related to the wave-length of the oscillations generated that the correct phase relation is produced between the anode and grid potentials. In a modulating circuit, the coil 3 receiving the highfrequency oscillations is split to interpose a lowfrequency transformer byepassed by condensers. In a detector, for example, in a supersonic heterodyne receiver, the grid circuit includes resistances R<1>, R<2>, Fig. 9, and is biased by connection to a point 15 of a filament resistance, a byepass condenser 14 being provided.

[Class 83 (iv)] A pipe of lead or lead alloy is marked by feeding it through a carrier or tubular guide 20 between a marking wheel 21 and a support wheel 23 located therein whereby distortion is prevented. The pipe may be marked as it comes through hollow ram 12 of an extrusion press in which the metal, in an extrusion pot 13, forms a pipe around the core 16 when the table 14 is raised by a hydraulic cylinder. The marking-wheel 23 and its support wheel may be mounted in a tubular guide 20 mounted in trunnions 19 on a bracket 18 of the press. To accommodate different sizes of pipe or to vary the degree of marking pressure, the support wheel 23 is adjustably mounted on an eccentric pin. Alternatively the marking &c. wheels may be mounted in a bridge piece 30 held by rods 32 in the extrusion press. Adjustment in this case is made either bv canting the bridge piece 30 when handscrews 39, 40 are relatively adjusted or by changing the distance pieces 41 which separate the wheel holders 30, Fig. 4. To make a double line of marking, two marking wheels 54, 55, Fig. 9 are adjustably mounted in a bracket 51 and backed by an adjustable support wheel 53. In this apparatus if one line of marking only is subsequently required the marking wheels and their holders are removed and one of them is used in the central aperture 61 provided in the bracket.
